Product Overview

The Yokogawa ANT401-50 S1 is a high-performance optical communication link for the Centum VP integrated production control system. This module converts electrical ESB bus signals into optical signals, enabling users to extend the distance between Field Control Stations (FCS) and remote I/O nodes. Utilizing fiber optic technology, the ANT401-50 S1 eliminates electrical noise interference and provides superior galvanic isolation across long-range industrial networks.

Technical Specifications

Engineering Advantages

• Superior Noise Immunity: Fiber optic transmission shields the communication bus from high-voltage surges and electromagnetic interference (EMI), common in heavy industrial environments.

• Long-Distance Scalability: Overcomes the distance limitations of copper ESB cables, enabling decentralized control architectures with I/O racks located kilometers away from the main processor.

• Space-Efficient Footprint: The ultra-slim 3.2 cm width maximizes rail space in crowded marshaling cabinets.

• Hot-Swap Capability: Supports redundant configurations, allowing replacement of a single module without interrupting the entire control bus operation.

FAQs

• Is the ANT401-50 S1 compatible with older Centum CS3000 systems?
  Yes, although primarily designed for Centum VP, this module is backward compatible with CS3000 systems that use the ESB bus architecture.

• What type of fiber optic cable does this module require?
  The ANT401-50 S1 requires single-mode fiber (SMF) with LC connectors to achieve the rated 5 km transmission distance.

• Does this unit include the required optical transceivers?
  Yes, the S1 designation ensures the unit comes as a complete, factory-tested assembly, ready for immediate installation.

• How does this differ from the ANT502 module?
  The ANT401 functions as the "Master" side (connected to the FCS), whereas the ANT502 typically acts as the "Slave" side (connected to the remote I/O node).
